Instructions.

Connect all of the Lidar cables to a USB port on your Raspberry pi or Jetson.

Make sure the USB cable is a data cable. If you have done this correctly, you should see two green lights as shown below and the lidar will spin.

At the Linux command, type:

usb-devices

You should see the following. If you do not see the Lidar (Manufacturer: Silicon Labs.) the Lidar is not connected properly. Check your connections and USB cable type.

Now make sure the data is coming through /dev/ttyUSB0.

cd /dev

ls

Install the Python3 packages.

sudo apt install python3-pip

sudo pip3 install rplidar

Python3 Code.

Create a python3 file called lidar2.py

from rplidar import RPLidar
lidar = RPLidar('/dev/ttyUSB0')

info = lidar.get_info()
print(info)

health = lidar.get_health()
print(health)

for i, scan in enumerate(lidar.iter_scans()):
    print('%d: Got %d measurments' % (i, len(scan)))
    if i > 10:
        break

lidar.stop()
lidar.stop_motor()
lidar.disconnect()

Run python code

sudo python3 lidar2.py
